EEPROM 6 click

EEPROM 6 Click is a compact add-on board that contains a serial EEPROM memory that operates from the 1-Wire interface. This board features the DS28EC20, a 20480-bit EEPROM organized as 80 memory pages of 256 bits each from Analog Devices. As a specific feature, blocks of eight memory pages can be write-protected or put in “EPROM-Emulation” Mode, where bits can only be changed from a 1 to a 0 state. It communicates with MCU at 15.4kbps or 90kbps over the 1-Wire protocol and has a 64-bit registration number that ensures error-free device selection.

Click library

  • Author : Nikola Citakovic
  • Date : Mar 2022.
  • Type : One Wire type

Software Support

We provide a library for the EEPROM 6 Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for EEPROM 6 Click driver.

Standard key functions :

Example key functions :

  • eeprom6_write_mem This function writes a sequential data starting of the targeted 16b register address of the targeted 16-bit register address of the DS28EC20.
    err_t eeprom6_write_mem ( eeprom6_t *ctx, uint16_t reg_adr, uint8_t *data_in, uint16_t n_len );
  • eeprom6_read_mem This function reads a sequential data starting from the targeted 16-bit register address of the DS28EC20.
    err_t eeprom6_read_mem ( eeprom6_t *ctx, uint16_t reg_adr, uint8_t *data_in, uint16_t n_len );

Example Description

This example demonstrates the use of EEPROM6 click board by writing string to a memory at some specific location and then reading it back.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
eeprom6_cfg_t eeprom6_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
eeprom6_cfg_setup( &eeprom6_cfg );
EEPROM6_MAP_MIKROBUS( eeprom6_cfg, MIKROBUS_1 );
if ( ONE_WIRE_ERROR == eeprom6_init( &eeprom6, &eeprom6_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
if ( EEPROM6_ERROR == eeprom6_default_cfg ( &eeprom6 ) )
{
log_error( &logger, " Default configuration." );
for ( ; ; );
}
log_info( &logger, " Application Task " );
}

Application Task

This example shows capabilities of EEPROM 6 Click board by writting a string into memory location from a specific address, and then reading it back every 5 seconds.

void application_task ( void )
{
log_printf( &logger, "Writing \"%s\" to memory address 0x%.4X\r\n",
strlen ( EEPROM6_DEMO_TEXT ) );
Delay_ms( 100 );
uint8_t read_buf[ 100 ] = { 0 };
eeprom6_read_mem ( &eeprom6, EEPROM6_TEXT_ADDRESS,read_buf,
strlen ( EEPROM6_DEMO_TEXT ) );
log_printf( &logger, "Reading \"%s\" from memory address 0x%.4X\r\n\n",
read_buf, ( uint16_t ) EEPROM6_TEXT_ADDRESS );
Delay_ms( 5000 );
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.EEPROM6

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. UART terminal is available in all MikroElektronika compilers.
